This technical solution can detect the working condition of the brake valve to ensure that the brake valve installed on the engine can work normally, thereby improving the safety performance of the engine.

[0004] The engine brake valve detection device disclosed in the above document has the following defects: during operation, the detection device needs to connect the air pipe joint to high-pressure gas and the cleaning liquid joint to cleaning liquid, and test the brake valve by synchronously spraying cleaning liquid and high-pressure gas. However, the waste liquid generated by cleaning contains pollutants such as oil, carbon deposits and metal debris, and directly discharging it through the waste liquid port will seriously pollute the environment.

[0031] When the waste liquid enters the filter assembly 6 from the waste liquid pipe 4, it first hits the conical block 609 at the top of the filter cartridge 604. Its conical structure converts the vertical downward flow of the waste liquid into a horizontally diffused uniform liquid curtain. The dispersed waste liquid permeates along the circumference of the filter cartridge 604. When passing through the filter holes on the side wall, large particles of carbon deposits and impurities are trapped on the outside of the cylinder by the filter holes of the filter cartridge 604.

[0034] By inserting the air supply pipe into the clamping ring 907 and then putting it on the port of the air inlet pipe 7, rotate the shell 901 to make it engage with the thread of the ring body 10 of the box body 1. At this time, the connecting block 906 on the inner wall of the shell 901 slides along the groove 908, and then converts the rotational torque into the axial thrust of the clamping ring 907, forcing the clamping ring 907 to radially contract and hold the air supply pipe tightly. As the thread is tightened, the clamping ring 907 continues to squeeze centripetally, so that the air supply pipe and the air inlet pipe 7 form a double seal. When installing the liquid supply pipe, insert the liquid supply pipe into the clamping ring 907 of another connecting component 9 and then put it on the port of the liquid inlet pipe 8, and then repeat the above steps.

[0036] Take out the brake valve to be tested and install it on the upper surface of the box body 1 through the mounting flange 3. Start the air supply device and the liquid supply device at the same time to make them spray at the same time. The working status of the brake valve is judged by testing the exhaust pipe 2, and the waste liquid enters the waste liquid pipe 4.

[0037] When the waste liquid enters the filter assembly 6 from the waste liquid pipe 4, it first hits the conical block 609 at the top of the filter cartridge 604. Its conical structure converts the vertical downward flow of waste liquid into a horizontally diffused uniform liquid curtain. The dispersed waste liquid penetrates circumferentially along the filter cartridge 604. When passing through the filter holes on the side wall, large particles of carbon deposits and impurities are retained on the outside of the cylinder by the filter holes of the filter cartridge 604.
